Thank you for this explanation. Yes of course, it's always good to explore every option.
However, this could be doable in the framework of various beyond the Standard Model theories (for instance in higher-dimensional frameworks).
Yes, in fact I was reading some article "Is Space Pixelated?" relevant to this, about new collaboration to try and tackle the quantization of gravity with string theory.
Which was what gave me the idea on writing this post. As I saw what they're doing as just another attempt to justify string theory.
But yeah, as you said "We may like it or not, but it is good to explore the possibility".
